member thereof may be extruded simultaneously f with the extrusion ofthe tube, it is equally applicable as a bottle nozzle closure means,provided, if desired, with a depending iiange similar to the upper endforming flange of a collapsible tube and also, if desired, with a nozzleextension projecting downwardly therefrom adapted to t within a cork tosecure it to the top of the bottle, or with the nozzle itself beingprovided with an extension going around the neck of the bottle. It isapparent when it is applied to cans and containers, either the whole canor container or the top of the container only may be extruded or formedsimultaneously with the formation of the nozzle and valve seat. Theinvention is adapted to dispense materials in powder form and moreparticularly is adapted to dispense materials in plastic, semi-plasticpartially liquefied form or liquid form and to provide at all times apositive closure for the nozzle means thereof which will not leak andhas been proven in tests not to leak with water, glycerine or othertypes of chemicals over a long periodof time.

While I am aware that [others have providedA nozzle closure means forcontainers, bottles, cans, tubes and the like having at least apartially spherical closure memberfunctioning as a valve and rotatablymounted in a suitably formed valve seat in the nozzle thereof, so farasv IV am aware these have been largely paper patentsA either impossibleto manufacture or only made at a great expense. I believe that I am thefirst o therefore to provide a nozzle closuremeans of this type whichmay be manufactured on a' practical commercial Abasis in the mannerdescribed herein and which is positively liquid, chemical and airresistant, and in which the valve forms preferably with a countersunkwasher a liquid chemical and air resistant positive joint when in closedposition and which may be readily manufactured in the simple mannershown herein and at a cost to make this type of a valve closure meanspossible under competitive condi- (Cl. 2li-148.2)

tions with other types of closure means now on the market.

As stated, hitherto the great difficulty with devices of thisdescription has been that the valve action is not air or liquidresistant. An object of my invention therefore is to provide a nozzleclosure means of this general description in which the valvev action isair, liquid and chemical resistant, and to this end I broadly provide,in

combination, a valve seat constructed of thin more, or less slightlyyieldable metal preferably in such a manner that it of itself may beslightly yieldable and construct the valve itself y preferably of apredetermined chemical resistant preferably Aslightly yieldablecomposition material which functions in combination with the t metal ofthe valve seat to forma substantially yieldable air` andliquid tightjoint at all times.

As a further precaution to insure an air tight, liquid tight joint I.preferably provide in the valve seat a countersunk preferably resilientfibre or other type of washer to positively bear against theoscillatable valve at all times to insure a tight joint, said washerbeing preferably countersunk Within the valve seat to keep it inaccurate alignment therein at alltimes. l

Great diiiiculty has been hitherto experienced in the manufacture ofcollapsible tubes, containers and closure means therefor, in providing aclosure joint resistant to the specific chemicals which may be containedwithin the contents of said cans, containers, tubes,\bottles or thelike.By employing plasticizable composition material I vhave been able toselect the materials of which the valve is made to make it resistantspecifically against the known chemicals in the contents of thecontainer, for instance, resistant to mild acids,alkzatlis,` alcohol,other solvents etc., and I therefore construct the` material of which myvalve is preferably f made of predetermined chemical characteristics tobe so resistant.

Further objects of myinvention are not only to provide a nozzle closuremeans of the type mentioned above which may be readily and simplymanufactured, but Aalso to provide one which will positively oscillateand whi h will function toy close or open the nozzleat a, lftimes. Ipreferably provide a turning lug' projecting lupwardly through the openend of the nozzle to' limit the oscillatable movement of the valvemember from an open to a closed position by the sides of said lugabutting .thesides of the upper end of the nozzle. I also provide meansto positively pivot the valve member on a defined horizontal axis sothat it may positivelyfunction at all times I construct it so that inclosed position the upper surface thereof projects substantiallytangentially from the top of the valve, so that it may be readily openedand provide the end of said lug having a tangential upper surface withan upturned portion to form an upwardly projecting tip or projection forthe ready oscillation of said valve from an open to a closed position.

Further features of my invention relate to the improved method ofmanufacture of and certain details of construction thereof so that itmay be readily manufactured in a commercial and practical manner. 'I'husI preferably mold the valve closure member with flattened opposite sidesto assist in forming an axis of rotation therefor and I providecentrally thereof outwardly projecting pivot lugs of a length with thesaid adjacent central valve portion of substantially the exact diameterof said sphere, so that if the valve be molded in hemi-spherical molds,the mold line will substantially pass through the centers of saidflattened side portions and said lugs to permit the ready removalthereof in an easier manner than if indentations were provided in saidflat portions which would be hard and almost impossible to remove fromthe molds, `and as the total length of said pivot lugs taken through theaxis thereof is not greater than that of the diameter of said sphere sothat they may be more readily removed from the molds. A further detailin the construction of my valve whichv makes pressure molding thereofpossible is the particular shape of the turning lug Ipreferablyemploywhich v includes a curved lower surface and a. flatupper surface substantially tangential to said spherical valve andterminating in an upwardly bent outer end meeting said lower surface toform an outwardly projecting lug being so shaped for a double purposenamely so that said integrally molded lug may be readily pivoted out ofa hemispherical valve mold by pivoting it therefrom on the point ofcontact of said mold with the lower surface of said lug, and to providea turning lug engageable by the finger which will oscillate the valve ineither direction.

A further feature of my valve construction is that I provide means forreadily pivotally attaching it on a fixed axis within the relativelythin upper portion of the nozzle wall, it being necessary to insert thevalve closure member within the partially spherical extruded recess orlower valve seat portion and press inwardlyV diametrically oppositeportions of said relatively thin nozzle upper wall against saiddiametrically opposite ilat valve portions to causethe pivot lugs to beimbedded within the nozzle wall to form4 sockets to receive said pivotlugs toprovide van axis of rotation for said valve.

Further features of the inherent construction of my improved closuredevice are that I pro provide a supplemental partially spherical upper`most a single operator.

valve seat portion for the upper portion of said valve to firmly retainit in position against said washer where employed and said lower valveseat portion formed during the extrusion process.

A further feature of my particular construction is that the countersunkannular recess for receiving the washer may be readily extruded in thevalve seat simultaneously with the extrusion of the nozzle and also ifdesired supplemental metal saving recess means formed in the lowersurface of said thickened portion to save the expense of additionalmetal or, if desired, the valve seat may be formed from an inwardlydepending annular flange projecting inwardly from said nozzle. Ifdesired, however, the countersunk washer receiving recess may be readilyformed in the upper portion as well as the lower portion of said valveseat during the extrusion process.

Further objects of my invention therefore are to provide a. novel methodof pressure molding of selected predetermined chemical resistantcomposition material in which a valve of the desired type may be readilymade at a minimum cost.

Further objects of my invention are to provide a novel type of extrusionapparatus and process for manufacturing the nozzle portion oi' myinvention with a suitable lower partially spherical valve seat portionin a thickened portion of said nozzle preferably having a countersunkwasher receiving recess therein and with the lower surface of saidthickened portion underneath said valve seat being partially removed tosave metal; preferably extruded simultaneously with a flange projectingoutwardly from a downwardly depending nozzle extension or a completecontainer or tube as shown.

Further features of my invention relate to the various features ofconstruction of my valve and nozzle `members hitherto described whichfunction to providea novel method of`assemblingthem into a nozzleclosure unit which may be entirely manual, semi-automatic, or completelyautomatic. 1

`Further features of my invention are to pro- `vide an improvedapparatus for such assembly,

being either fully automatic or requiring at the By providing the valvestructure hitherto described and the valve seat structure also describedin said nozzle, I have provided a construction whereby the nozzle may bereadily mounted on a rotatable ring or conveyor and the followingsequence of steps performed thereon during intermittent intervals ofmovement of said rotatable ring or conveyor, namely, (1) the mounting ofsaid nozzle on suitable means on said conveyor, (2) manufacture, shapingand insertion of the fibre washer within the countersunk valve seat inthe lower valve seat portion of said'nozzle or upper valve seat portion,if desired, (3) the insertion of the oscillatable valve closure memberso as to abut said washer and lower valve seat nozzle portion in correctalignment, (4) the downward crimping of said nozzle upper wall toprovide a partially spherical upper valve seat portion enclosing saidvalve member and rmly securing it against said washer and said lowervalve seat portion, (5) the inwardly pressing diametrically oppositeflattened valve portions to form flat abutting surfaces to accuratelyalign the axis of oscillation of said valve Awithin said nozzle and tosimultaneously press the pivot lugs where employed into the relativelythin nozzle wall to form sockets therein to receive said pivot lugs topositively provide an axis of rotation for said valve member to keep thedischarge passage thereof in the desired alignment with the dispensingholes at the upper and lower ends of said nozzle when in open position,(6) oscillating said valve turning lug to move said valve member to aposition closing said nozzle either by hand or by automatic means ifdesired, (7) again crimping the upper portion of said nozzle wall oversaid valve member to align said hollow upper valve seat portion and sealsaid valve in ashipping position and, (8) removing said assembled nozzlefrom said conveyor or ring. If desired, however, the first and secondcrimping steps and inwardly pressing axis forming steps may be performedsimultaneously, the portions of the upper side wall of the nozzle beingpressed inwardly against the flat diametrically opposite valve sideportions to provide the flat abutting surfaces and lug sockets toprovide a true axis of oscillation for said valve member while the upperend of said nozzle wall portion is being bent downwardly over the uppersurface of said valve to form the upper valve seat portion, it beingapparent that these two operations are performedl simultaneously withthe crimping step, preferably maintained slightly longer. In mypreferred embodiment, I have shown mandrel means for supporting thenozzle during this sequence of steps and indexing means to advance saidring or conveyor amounts to progressively change stations to permit theabove described sequences of assembly stepsto be performed thereonduring the intervals between said progressive advancements. It isobvious that any type of continuous conveyor may be employed and in mypreferred embodiment I preferably employ a ring rotatably mounted on asuitable standard on which the desired tools to accomplish the stepsdescribed are mounted on the respective stations thereof to perform theactual work thereon at these stations between the intermittent intervalsof movement of said conveyor or ring.

Further features of my invention are therefore to provide a novel typeof apparatus for this method of assembly which may be done either byhand, semi-automatically, or fully automatically to save the number ofoperatives required.

While my inventionis particularly applicable for use in the manufactureof collapsible tubes, cans, containers, etc., which may have either theupper portion or entire body thereof simultaneously extruded with theformation of the nozzle, it is apparent that my invention may be equallyapplicable to bottle closures which may also be provided with anoutwardly projecting annular flange analogous to a can or container topor collapsible tube top and if desired the nozzle portion may beextended below said spherical valve seat portion in the extrusionprocess to provide means whereby an annular cork or other device may beemployed to surround said extruded nozzle for insertion within a bottleneck. If desired, the entire valve closure member may be constructedhollow and the valve seat portion of the nozzle similarly enlarged ifnecessary so as to receive and dispense a predetermined bulk of powder,liquid, or other material contained within said hollow valve. For thispurpose I preferably provide the hollow valve seat portion with a singledischarge end and I preferably construct the cooperating surfaces of thenozzle side wall and the nozzle inlet and outlet holes so that thepredetermined'bulk holding hollow valve may be moved to three positions,namely (1) a position to fill said hollow valve when the bottle orcontainer is in inverted position, (2) to a loaded position in which thehollow valve is turned so that the discharge vent is completely sealedby the side wall of the nozzle, which position may provide a convenientloaded position taking a much less time to dispense from than if firstfilling the hollow valve portion and immediately discharging it, and (3)to a position bringing the discharge vent in the hollow valve memberinto substantial alignment with the nozzle discharge hole fordischarging. This specic embodiment of my invention is specificallyadapted for use ,when serving liquors at a crowded bar, as thebar-keeper may at intervals load up the hollow valve member and pivot itto loaded or cocked position again ready for immediate dispensing.

In the drawings, wherein like characters of reference indicate likeparts throughout, I0 generally indicates a nozzle closure means forcontainers, constructed in accordance with my invention. The nozzleclosure means I0 may have the annular flange I2 projecting radiallyoutwardly and also downwardly therefrom to which the side wall I4 of thecollapsible tube may be attached, or if desired, my nozzle closure meansI0 may be employed as a bottle top as shown in Figs. 11 and 13. Myimproved nozzle closure member I0 includes a preferably hollowpreferably extruded preferably metal nozzle member I6, preferably havingthe lower portion I8 thickened as at 20 and having a central dispensinghole means 22 therein, said lower portion I8 preferably having apartially spherical preferably slightly yieldable lower valve seatportion 24 on the inner surface thereof extruded thereon at the sametime that the nozzle portion I6 is being extruded, and also extrudedsimultaneously with the flange I2 if employed, and the container or tubeside wall I4 or, if desired, simultaneously with the nozzle extension 26as shown in Figs. 11, 13 and 15. In the embodiment shown the lower valveseat portion 24 is preferably substantially hemispherical. The flange I2may, as shown in Fig. 1, be the means to secure said nozzle member to acontainer, bottle, tube, can or the like such as by forming the wall I4integral therewith as shown in Fig. 1 or other means may be provided, ifdesired, to secure said bottle, tube, can, container or the like, suchas by providing an annular cork member 28 adapted to surround theextruded nozzle portion 26 as shown in Figs. 11 to 15 adapted to beslightly yieldable contained within the bottle neck.

My invention broadly includes a preferably substantially spherical valveclosure member 32 mounted within the upper end of said nozzle I6 andprovided with a discharge vent or passage 34 and a suitable axis ofrotation 36 and preferably a turning lug 38 whereby said valve closuremember 32 may be oscillated to positions bringing the discharge vent orpassage 34 thereof in alignment with the inletuhole 22 in the lowerportion of said nozzle and/or the outlet hole 40 in the 44 formed insaid nozzle. [Saidvalve seat 44 includes the lower valve `seat-"portion24 and the.` upper valve seat portion46 to 'be described...`

Where a collapsible tube ,is employed I preferably suitably countersinkthecircular washer!! in a countersunk recess 42 4in the lower valveseatportion 24, but may, if desiredas shownin Figs. l

and 17 countersink saidwasherrecess the upper valve seat portionofthejnoz'zlery nozzle member I6and simultaneously provide. it with alower valve seat portion 2,4 in a Athickened portion of said nozzle andI may simultaneously therewith extrude the annular washer receivingrecess 42 therein. In order to-save metal I also preferably provide Ymetal saving recess means preferably in the form of an annular groove 48on the lower surface of said thickened portion or I may, as shown inFig.` 10 so construct the recess 48 as to substantially form as thelower valve seat portion 24 thev annular slightly yieldable flange 24'projecting arcuately inwardly substantially centrally of the `side wall50 of lsaid noz-- zie. In my preferred embodiment each recess, namelythe washer receiving recess 42 and the annular metal saving recess 48,are preferably concentric with the dispensing hole lmeans 22 in thelower portion of said nozzle substantially centrally of the lower.substantially hemi-spherical valve seat portion 24. After the extrusionprocess, the upper portion 52 of the side wall 50 of said nozzleprojects substantially vertically upwardly from the upper edge of saidlower valve seat portion 24. In the embodiments shown in Figs. 1 and 22,the annular flange I2 projects outwardly and downwardly from the lowerportion 54 of said nozzle wall 50.

As stated hitherto, in order to prevent leakage through my improvedvalve closure means i0, I preferably provide `a washer 56, mounted insaid countersunk annular washer receiving recess 42, preferablyconstructed of fibre, leather, rubber or other suitable preferablyresilient material of a greater thickness thanthe `depth of lsaid recess42 to at all times closely engage the oscillatable valve closure member32 to form an air and liquid tight seal at all times therewith, andbeing constructed preferablyof material where liquidsare employedresistant tothe chemical constituents thereof. e i

In the preferred embodiment shown, I preferably extrude the nozzleportion i6 and integral flange l2 where employed and tubev or container.

side wall I4 where employed or nozzle extensionV 26 where employed ofmetal. Andwhereas I may make my improvedvalvemember 32 of metal to ichemicals contanedfin the contents of the container, such as mildacid,weak,or 'strcng`alkali, alcohol, or other solvents, etc.{Said-improved valve member 32 is pivotally oscillatablymounted on saidvalve seat 44 on a horizontal axis 36 against said washer 56. In orderto provide a suitable axis of rotation and a construction which may bepressure molded in two superimposed substantially hemi-spherical molds,I provide diametrically opposite flattened side portions58 on said valvemember 32 as more particularly shown in Figs. 4, and provided with pivotlugs 60 preferably having rounded ends as shown and preferablyprojecting outwardly centrally of said fiattended side portions58, andof a length with said adjacent centrall valve portion, of substantially,the diameter of the sphere of which my improved valve member ispreferably molded for a double .o purpose, (1) so that lugs 60 will notbe of such a v Y '-.g'length as to prohibit their being removed from Asto be explained laterinv connection with# Figs. 19 to 22, I preferablyextrude my improved the4 molds, they VVbeing normally so placed as to`lie substantially on the mold line between the two vhemi-sphericalmoldsand, (2) so that they may be readily dropped to the desired feedingposition within the diameter of said nozzle against the Vpartiallyspherical lower valve seat portion 24 thereof. Portions of said nozzlemember side wall 50 are diametrically pressedatly inwardly as at 59against said flattened valve sides 58 to assist in providing an axis ofoscillation for said valve portion 32 and to form sockets 66 therein asshown in Fig. 4 to receive said pivot lugs 60 diametrically of said wall50 to provide an axis of oscillation for said valve member 32, and theupper portion 52 of said vertical nozzle member side wall is preferablycrimped downwardly over said rotatable valve member to form a hollowpartially'spherical upper valve seat portion 46 having a centraldispensing hole means 40.

Said valve member 32 is also provided on the upper end thereof with a-turning lug 38. Said lug 38 is preferably formed with a curved lowersurface 12 and a flat substantially tangential upper surface 14,terminating in an upwardly bent rounded outer end 'I6 meeting saidcurved lower surface l2 to form an outwardly projecting lug 16projecting radially outwardly from said valve member 32, being thusshaped for a double purpose, (l) so that said turning lug may be readilyremoved from a hemi-spherical mold on pivoting said closure membertherefrom, the inner end of the lower-curved portion 32 forming an axisfor said pivoting, and (2) to provide means whereby 'the closure member32 may be readily oscillated in either direction, namely, to open bygrasping underneath the lower curved portion and to close by graspingthe inner portion of the up- `wardly projectinglug 16 thereof, thusproviding `means to oscillate said valve an amount limited .by saidturning lug 38 abutting oppositeedges of said dispensing hole means 40in said hollow crimpedupper valve seat portion 46. As stated, said valvemember 32 is also preferably provided with a discharge vent 34 either atone end thereof or passing therethrough of such a size and locatedrelative to the center of said valve, and said nozzle` side wall 50 andthe upper and lower dispensing holes 40 and 22 respectively of saidnozzle I6 are of such a size and shape that said discharge vent orpassage 34 may be rotated into alignment with the respective dischargehole valve seat 44 with the outwardly projecting end 1620i saidlugabutting one edge of said upper means 40 and 22 in the hollow ends ofsaid nozzle turning lug substantially abutting the other end of saidupper valve seat hole 48, if desired.

While the improved washer 56 is highly desirable, it may, if desired, beomitted or inserted as shown in Fig. 15 in a suitably countersunk hole42 in the upper valve seat portion 46. While I have shown, for reasonsto be explained, my improved type of means for oscillatably pivotallymounting the valve closure member 32 in said nozzle, in place of thepivot lugs 68 hitherto described, I may as shown in Fig. 9 providesuitable sockets 66 in the attened side portions 58 of the valve memberto receive the pivot lug 66' formed from the nozzle side wall 52 whendiametrically opposite portions of said side wall are pressed inwardlyas hitherto explained The vent or passage 34 of my improved valve memberis preferably shown located substantially near the center thereof andpassing therethrough but it is obvious that if desired it may be locatedalong the side thereof as suggested in Fig. 13 or through any portionthereof. It is also obvious that the valve seat 44 including the lowervalve seat portion 24 and the upper valve seat portion 46 may be formedin any other desired manner than in the manner shown. While I preferablyemploy an extruded metal nozzle it is apparent that if desired thenozzle portion may be molded or extruded out of composition or otherlike material, cast Vor otherwise fabricated and while I have preferablyconstructed my improved valve closure member of molded compositionmaterial, it may if desired be suitably fabricated in any desired mannerout of other material. As explained hitherto, by constructing the valveseat of slightlyv yieldable metal material and by constructing the valveof slightly yieldable composition material I have found that a truecooperation exists therebetween, providing substantially an air andliquid proof joint at all times and one in which there isl substantiallyno wear as in a metal to metal contact, permitting the use of myimproved nozzle closure means over a long period of time. In order thata more slightly yieldable lower valve seat portion 24 may be provided, alarger metal saving recess 48 may be provided and particularly whenextruding aluminum I may extrude Vthe lower valve seat 24' in the formof a slightly yieldable annular flange depending arcuately inwardly fromthe center portion of the nozzle side wall to the central dispensinghole 22.

As explained, I have shown in Fig. the axis of rotation of the valvemember 32 on said nozzle member I6 formed not only by the flattenedlside portions 58 of the valve and adjacent flat portions 69 of thenozzle side wall but in place of the pivot lugs projecting outwardlyfrom Athe valve into sockets 66 vformed in the adjacent nozzlewall, Ihave provided the recesses 60.' in said valve to receive the pivot lugs66' formed in said nozzle side wall when said nozzle side wall ispressed inwardly on diametrically opposite points thereof in the mannerhitherto explained and as shown in Fig. 9.

I have shown in Figs. 11 to 18 various forms yof my inventionparticularly adapted as closures for bottle tops: the embodiments shownin Figs. 11 to 14 being constructed substantially similarly to myinvention as shown in Fig. l applied to a collapsible tube except thatthe side wall of the tube I4 is omitted from the flange l2, the nozzle I6 is extended downwardly as at 26 and provided with an annular cork ring28 'for securing my improved closure means within the bottle neck 30.

In the embodiment shown in Figs. 1l and 12,

the discharge passage 34 of said valve may be tapered as shown and of asize to dispense a single drop at a time from the interior of saidcontainer 3|. The embodiment shown in Figs. 13 to 14 may as shown beapplied to the neck 30 of a liquor bottle and in addition to thedischarge passage 34 is provided with the air inlet passage 18 torapidly admit air within the bottle to permit the rapid discharge of theliquid contents thereof through the discharge passage 34 of said valvemember 32. It is apparent, however, that the discharge passage 34 may beconstructed at the side of the closure instead of through it as the airinlet passage 18 shown in Fig. 14 or that Asaid discharge passage 34 maycomprise any desired part of a sphere up to a hemisphere. If thedischarge passage 34 be located at the side however and substantiallyenlarged, it is not anywhere near so desirable as the type specificallyshown herein for ease of manufacture and assembly but may for somefeatures of myA invention be provided.

I have shown in Figs. 15 to 18 embodiments of my invention adapted todispense a measured dose of predetermined bulk from the container andfor this purposeI have enlarged the vent 34 so as to substantially takeup the entire interior of said valve member 32 and I havecorrespondingly enlarged the adjacent substantially spherical valve seatportion 44 of said nozzle Wall. The hollow closure and vent arepreferably of such a size and shape and said nozzle side wall and lowerand upper dispensing hole means 22 and 40 thereof respectively arepreferably of such a size and shape that said hollow closure vent 34Ymay be rotated into alignment with said lower dispensing hole means 22when said olosure means is inverted to permit reception of said measureddose-or quantity within said hollow closure member with said turning lug38 abutting one .edge of said nozzle hole means 40, oscillated againstthe friction of said composition closure member 32 against saidy metalvalve socket 44 `to bring said hollow closure vent 34 opposite saidnozzle side wall 50 into intermediate loaded or cocked dose ordrink-holding position, so as to be frictionally retained therein, orrotated into alignment with said upper dispensing hole means 40 to expelsaid measured dose therethrough with said turning lug 38 substantiallyabutting the other edge of said upper nozzle hole means 40. I haveshown. in Fig. l5 this embodiment of my invention applied to a neck 30of a liquor bottle provided with the elongated nozzle extension 26 andbeing secured within said neck by the annular cork 28, the flange l2 inthis instance being omitted: While it is possible to extrude this nozzleit is not so easy as the extrusion of the other nozzles shown anddescribed hitherto and if desired the nozzle portion I6 may be cast,stamped or otherwise shaped for this embodiment. I have shown in Figs.17 and 18 an embodiment of my invention similar to the embodiment shownin Figs. 15 and 16 but particularly adapted for dispensing a measureddose of powder. In this instance the lower nozzle discharge port 22 ismade relatively small so that the closure member 32l may be oscillatedor rotated into three positions, namely the filling, loading, anddispensing positions as shown in full or dotted lines respectivelytherein. In this instance the lower nozzle extension 26 is widened tofit outside of the neck 38 of the bottle and is provided at its lowerextremitywith the inwardly vprojecting lip 29 providing means to securemy improved nozzle closure member Il) to the bottle. In this embodimentthe nozzle means I6 may be conveniently molded.

As stated hitherto, I have preferably provided in the specific detailsof my construction both a valve closure member 32 which may be readilyfabricated in a simple manner and a nozzle portion I6 which may be alsoextruded or otherwise fabricated in a simple manner, the nozzle beingpreferably constructed of metal and the valve member being preferablyconstructed of molded composition material so as to yieldingly abut eachother and form an air and.liquid tight non-Wearing joint in use betterthan it is possible to obtain by composition against composition ormetal against metal. I have also constructed the details of my improvedvalve structure with a view to a simple method of its manufacture. Ithus, as explained, provide a substantially spherical slightly yieldableclosure valve member preferably consisting of heini-spherically moldedpredetermined chemically resistant composition material having thediametrically opposite at sides 58, having the pivot lugs 60 projectingoutwardly centrally thereof, of a length with said adjacent centralvalve portion of `substantially the diameter of said valve for easierremoval from a hemi-spherical mold and for easy insertion within saidnozzle member with said mold line passing therethrough and a turning lug38 at the upper end thereof preferably having a curved lower surface 12and a flat substantially tangential upper surface 14 terminating in anupwardly extending outer end 16 meeting said curved lower surface 'I2 toform an outwardly projecting turning lug 16 shaped to be removed onpivoting thereof from said hemispherical valve mold and a discharge vent34 therein or therethrough substantially at right angles to thediametric axis of said pivot lugs E0. As stated hitherto, my improvedvalve closure member may be constructed in this specific manner out ofany suitable material, but for the reasons described and for theadditional reason that composition material may be brightly pigmented orotherwise colored with any desired color to provide an attractivecontrast with the metal nozzle, I preferably construct it ofpredetermined chemical resistant composition material. of rotationthereof by providing thesubstantially spherical closure member withdiametrically flattened sides 58 and pivot lugs 60 projecting outwardlycentrally thereof of less total length than the diameter of said spherefor easy withdrawal from the mold and insertion within the nozzle, it isobvious that in place of pivot lugs I mayprovide the pivot recesses 60as shown in Fig. 10 or other types of pivot means, such recesses orother types of pivot means being not however so easily withdrawn fromthe molds, and I may in place of the side portions 58 and lugs 6Dprovide any type of oscillation axis forming means. While the turninglug 38 at the upper end of said closure means is preferably constructedin the manner described with a double function of easy removal from themold and being operable to be actuated by a finger to readily oscillatethe valve in either direction, it may if desired be constructed in otherways than in the specific manner shown.

As stated hitherto, for the reasons given above and as a plasticcomposition material may be readily pigmented or otherwise colored toprovide an attractive appearance, I preferably construct While I havepreferably formed the axis my substantially spherical closure member ofhemi-Spherically molded, predetermined chemical resistant compositionmaterial. While any suitable type of plasticable composition materialmay be employed, I preferably employ one of insoluble phenolformaldehyde, intermediate condensation product type such as Bakelite,or insoluble urea formaldehyde intermediate condensation product or aninsoluble cellulose acetate product or in fact any suitable type ofmoldable preferably resilient composition material. With the widespreadrange of composition materials possible, it is obvious that I am able toselect a composition material particularly resistant against thechemicals in the known contents in the container for which my improvednozzle closure means is desired to be used. Thus for instance, if itwould be desired that the closure member be resistant to alkali or weakacid, I preferably employ an alkali or acid resistant insoluble phenolformaldehyde intermediate condensation product specially treated to makeit acid and/or alkali resistant. If I desire a valve member resistant toalcohol, I preferably employ an insoluble urea formaldehyde intermediatecondensation product or I may if desired employ a cellulose acetateproduct or any of a great many possible composition materials preferablyso selected as to be resistant to the particular chemicals in thecontents of the container.

Employing these materials it is possible to 'manufacture my improvedvalve member 32 by pressure mplding in two superimposed hemisphericalmolds. The henri-spherical molds are preferably so shaped as to providethe flattened. sides 58 and the pivot lugs 60 projecting outwardlytherefrom substantially centrally between the hcmi-spherical molds of alength with said adjacent central valve portion of substantially thediameter of said valve and molds. It is apparent therefore that the moldline will be formed substantially centrally of the flattened portions 58and through the pivot lugs 60 to permit the easy Withdrawal of saidpivot lugs from the mold. Thus the particular construction I employ toprovide an axis of rotation for the valve member is constructed with aview of its easy manufacture or molding.

One of the molds is also shaped to provide said closure member with aturning lug 36 at the upper end thereof in the manner hitherto describednamely preferably with a curved lower surface 12 and a flatsubstantially tangential upper surface 'I4 terminating in an upwardlybent rounded outer end 16 meeting said lower surface to form anoutwardly projecting turning lug 16. To provide the discharge ventpassage 34 I preferably suitably mount within the molds substantiallycentrally thereof as desired suitable pin means. When the molding iscomplete I separate the hemi-spherical molds, remove said pin means pinmeans may project through the molds to assist holding them togetherandmay be removed prior to separation of the bami-spherical molds.

I have shown in Figs. i9 to 20 an improved extrusion press forsimultaneously manufacturing my improved nozzle blank member andsimultaneously therewith if desired the annular wall I2 andsimultaneously therewith the side wall I4 of a collapsible tube orcontainer. For this purpose I provide a female die having an outwardlytapered face 82 for receiving a round, annular or otherwise shaped tubeblank 84 and an annular nozzle forming hole 86 depending centrallytherein having a cylindrical outer surface 88 and a convex partiallyspherical valve seat forming inner surface or protuberance 90. To formthe annular washer receiving recess 42 I preferably provide said femaledie with the annular washer recess forming projection 92 thereon, Ifdesired, as shown the valve seat and female forming protuberance ismounted on a plunger 95 slidable within the central bore 81 in said die,a portion of which forms the outer surface of said annular hole 86, saidplunger being provided at the lower end thereof with the annularshoulder 94 `adapted to abut the shoulder 06 on the lower portion ofsaid die, said shoulder 84 being adapted to be actuated by the liftercam 98 for a purpose to be described. I provide -a cooperating male die|02 of slightly less diameter where a collapsible tube side wall I4 isto be formed than that of said cooperating side wall 83 of said femaledie and having a cooperating tapered face |04 to cooperate with thetapered face 82 to form the annular flange I2 and to simultaneouslyextrude said tube side wall or body I4 in the space between the sidewall of said male die |02 and the side wall 83 of said female die and acenter portion |08 shaped to form with the outer surface 88 of theannular nozzle forming hole 86 in said nozzle I6 and with the innersurface or projection 80 of said annular hole 86 the partially sphericallower valve seat portion 24 on the inner surface of said nozzle, saidcenter portion |06 of said male die being preferably provided with anannular metal saving recess forming projection |08 thereon substantiallyopposite and inside of the outer edge of saidnozzle forming hole 86. Thecenter portion |06 of said male die may be provided with the plunger |I0slidably mounted in the central bore ||2 of said male die |02 and havingits up and down movement limited by the lug |I4 projecting inwardly in avertical slot |I6 in said plunger ||0 to limit the up and down movementof said plunger I I0 and attached male die center portion |06 for apurpose to be described.

As shown in Fig. 20 when the male die member is compressed downwardlyagainst said blank 84, it presses a portion of said blank against thelower tapered surface 82 of the female die to form the annular shoulderI2 hitherto described and the tube body I4 where employed issimultaneously extruded upwardly in the space I|8 formed by thedifference in diameters between the hollow female die portion 83 and themale die |02 and a portion of the blank is extruded downwards againstthe cylindrical outer side wall 88 of said annular nozzle forming hole86 to abut the central nozzle forming projection 90 of the female die toform said nozzle I6 and valve seat. the annular projection 92 of saidprojection 90 forming the annular washer receiving recess 42 in saidlower valve seat portion 24 and said annular projection |08 forming anannular metal saving recess 48 in the under surface of saidsimultaneously formed partially spherical lower valve seat portion 24,the substantially vertical cylindrical upper valve seat portion 52 beingformed between the outer surface of the projection 00 and the outersurface 88 of the annular female die hole 86. After the tube and nozzlewith its integral partially spherical lower valve seat portion 24 havebeen simultaneously extruded as shown in Fig. 20 and the male die memberhas been partially removed, the lifter cam 98 raised to simultaneouslyremove the projection 90 upwardly to free the extruded tube I2, flangeI4 and nozzle I6 from the female die, the tube I2, the flange I4 andnozzle I6 are removed from said male die by air pressure forced down theduct I|2 in the male die, said air'pressure forcing the plunger |I0downwards to lower said center portion |08 against the thin disk or web|20 formed centrally of said lower valve seat portion 24 to free saidextruded tube flange and nozzle from said male die. It is thus obviousthat I have produced by placing a tube blank in the die and extrudingsaid blank to simultaneously form a tube body I4 and integral preferablytapered annular shoulder I2 and integral nozzle I8 secured theretohaving a partially spherical lower valve seat portion 24 on the innersurface of the thickened lower portion of the nozzle provided with anannular washer receiving recess 42 therein and a metal saving annularrecess 48 on the under surface of said thickened lower portion, and asubstantially vertical inner surface 52 above said valve seat, that Ihave provided a nozzle portion for a container or a collapsible tubecomprising an extruded body I4, an integral annular flange I2 attachedto said body I4 and an integral nozzle I6 attached to said annular4flange I2 having a side wall 50 having a. partially spherical lowervalve seat portion 24 on the inner surface of the thickened lowerportion I8 thereof preferably adjacent to said tube flange I2 having acontinuous annular washer receiving recess 42 in said partiallyspherical lower valve seat portion 24 formed therein and a metal savingannular recess 48 in the under surface of said thickened lower portionI8, the upper surface of which forms said lower valve seat portion 24with the inner surface of said side wall 50 projecting substantiallyvertically upwardly above said lower valve seat portion 24 and as showna film or disk |20 filming over the lower hole 22 of said nozzle. Inpractice this film or disk is then removed and this intermediateextruded product is then ready for the attachment of the valve closuremember described above therein.

Further features of my invention relate to the novel type of apparatusand the method I employ in assembling the valve closure member 32 withinsaid nozzle I8. It is obvious that both the nozzle member I6 and closuremember 32 are designed with the view of permitting the easy assemblythereof. I have shown in Figs. 23 to 29 a suitable type of apparatus forthis purpose which broadly includes a conveyor |22, movablepredetermined amounts to permit the following sequence of steps to beperformed thereon substantially simultaneously during the intervals ofmovement thereof. The entire sequence of steps of assembly are performedon a series of nozzles in one position and the conveyor is moved ahead apredetermined amount and the same sequence of steps is performed allover again on the next adjacent nozzle thus making a sequence of stepsto be performed successively on the same nozzle throughout a cycle ofassembly on the conveyor. Broadly, I load the free ends |24 of saidtubes or nozzles on the holders which preferably contain suitablemandrels |26 mounted at successive spaced distances along said conveyorand I employ mandrel means in the claims to designate any suitable typesof holders.

In my preferred embodiment the sequence of assembly steps comprises thefollowing: (l) loading the free end |24 of said collapsible tube ornozzle I8 on. said mandrel means |26; (2) inserting the annularpreferably libre washer 56 in said lower partially spherical valve seatportion 24 where the washer be employed and within said annular washerreceiving recess 42 where the countersunk washer recess 42 beemployed;(3) inserting said substantially spherical preferably resilient valveclosure member 32 within said nozzle on said lower valve seat portion 24over said washer 56 with its turning lug 28 in an upright positionthereby providing the discharge projecting upwardly therethrough; (5)pressing its inwardly dlametrically opposite center portions of saidrelatively thin nozzle upper wall as at 59 against said diametricallyopposite flattened valve portions 58 to form sockets 66 in said nozzlewall 5l to receive said pivot lugs 60 to provide a horizontal axis ofrotation for said valve member 32; (6) oscillating said valve turninglug 38 to move said valve member so that the discharge vent or passage34 thereof will be opposite the nozzle side wall 58 in a positionclosing said nozzle; (7) again crimping the upper portion of said nozzlemember upper side Vwall downwardly as at 4i over the upper surface ofvalve member 36 to realign said hollow upper valve seat portion 46 andseal said valve in a shipping position; and (8) removing said assembledcollapsible tube 4from said mandrel means, where employed, on'saidconveyor. If desired, step 2 of inserting the annular washer may bedispensed with where said washer is not employed. Said annular washerreceiving recess 42 may be dispensed with if it is not desired toaccurately align the washer in said lower valve seat portion. Steps 6and 7 of oscillating said turning lug to close said nozzle and againcrimping the upper portion of said nozzle may be dispensed with ifdesired, or if desired as shown in an embodiment of my invention I maysimultaneously press inwardly the diametrically opposite portions of theliu - preferably continuing the crimping after the diametric inwardpressure has been released if desired to firmly seat the valve 32 withinits valve seat 44. Thus this simultaneous operation may be substitutedfor steps 4, 5, 6 and '1.

While the improved hitherto described method may be performed by hand orby machinery in the aforedescribed sequence of steps, I preferably mountsaid nozzle or tube on said conveyor and move said conveyorpredetermined amounts to permit said sequence of steps to be performedthereon preferably simultaneously` between the intervals of movement ofsaid conveyor. I have shown in Figs. 23 to 29, however, an improved typeof assembly apparatus for use in carrying out said method comprising acentral standard |28, a ring or conveyor |22 rotatably mounted in anysuitable manner on said standard |28. I have mounted a plurality ofnozzle receiving mandrel or holding means |26 at equally spaced pointsof said conveyor or ring. In the embodiment shown I have arranged foreight steps to be performed on the conveyor and I have shown twomandrels for each step, although if desired one or any number of mandrelmeans may be provided for each step, the ring or conveyor belng advancedproportionate amounts. I thus provide on adjacent portions of saidstandard a nozzle loading station I, a washer loading station 2, aclosure member loading station 3, a crimping station 4, a pivot fixingflattening station 5, a valve closing station i, a second crimpingstation 1, and an unloading station 8.

As indicated hitherto, my improved .apparatus may be either operatedentirely by hand or partially by hand and partially by machinery thussemi-automatically, or may be operated entirely by machinery orcompletely automatically. In any event in order that the conveyor orring may be moved forward predetermined amounts such as to move from onestation to the next, I have shown in the drawings suitable indexingmeans for this purpose to advance said ring equal or other suitableamounts to progressively change stations and for this purpose I havepivotally mounted the lever |34 having the handle |35 projectingoutwardly from said ring |22 on the lower surface of said standard as at'|38 and I have pivotally mounted substantially adjacent to the outeredge of said ring on said lever |34 the pawl |4II adapted to registeragainst the ratchet teeth |42 projecting outwardly from said ring |22substantially opposite each individual `imandrel and thus being providedin the embodiment shown with two mandrels with adjacent ratchet teethV|42 for each respective station. In order to accurately index or stopthe ring so that the mandrel thereof |26 with attached nozzle Ii beexactly opposite its appropriate tool at the desired station, I providethe spring actuated plunger |44 mounted on said standard overlying ahole |46 for receiving the end thereof in said ring so as to stop eachdesired mandrel exactly opposite its respective station and overhangingtool where employed.

I have shown in the drawings the loading step at the loading station #las being done by hand although if desired this may be doneautomatically. I have also shown the insertion of the washer to be doneby hand at the washer loading station #2 although if desired the washermay be individually formed from` a continuous strip of strip materialand automatically inserted in the valve seat portion and in thecountersunk annular recess 42 thereon by machinery. I have shown in thedrawings the valve member 32 inserted on the lower valve seat portion 24within said nozzle I6 by hand, although it is obvious that by chutes orother means this may be entirely done by machinery at valve loadingstation #3. It is also obvious that in place of the hand conveyor movingand indexing mechanism shown herein an automatically movlngand indexingmechanism may be provided by machinery. I have shown at station 4crimping means such as the punch |48 provided with the central hole |58,provided with an interior concaved annular crimping surface |52 adaptedto abut the upper surface of the nozzle member wall 52 to crimp theupper portion of said nozzle member upper side wall 52 downwardly overthe upper surface of said valve member to form a hollow partiallyspherical upper valve seat portion 46 having central dispensing holemeans 48 with said turning lug 38 projecting upwardly therethrough. Ihave shown the punch member |48 in the drawings provided with the rackteeth |54 on the upper portion thereof and the pinion |56 mounted insaid standard to actuate said rack teeth. 'Ihe pinion |56 may be rotatedfor this purpose either by hand or by suitable machinery, and I haveshown a similar rack |54to actuate the other means at stations 5, 6, and1 about to be described. At station 5 I provide diametrically inwardlypressing means mounted on said standard at said pivot fixing flatteningstation to function with said adjacent mandrel to press the nozzle sidewalls inwardly at diametric points thereof against the flattened sides58 of said valve' to form the adjacent attened sides 58 and the sockets66 to receive the pivot lugs 68. While any means may be provided forthis purpose I' have shown diagrammatically in Fig. 26 suitable plungers|58 at diametrically opposite points of said nozzle provided, ifdesired, with the central sockets |68 in the ends thereof, and thevertical cam holes |62 therein to be actuated simultaneously inwardly onthe simultaneous downward depression of the vertically reciprocal cammeans |64 to accomplish the above results at station 5. I have shown instation 6 means |55 mounted on said standard to function with saidadjacent mandrel at said valve closing station 6 to oscillate said valve32 to a closed position, in the specific embodiment comprising ahorizontally reciprocal plunger |64 having a cam hole |66 thereinadapted to be moved inwardly by the vertically reciprocal cam |64, theend |18 of said horizontally reciprocal v plunger |64 being adapted toabut the outwardly projecting surface 16 of said turning lug 38 to movesaid turning lug and oscillatesaid closure member 32 from the openposition shown in Figs. 25 and 26 to the closed position shown in Figs.27 and 28 to bring the ends of the discharge passage 34 of said valvemember 32 in a closed position opposite the side wall 58 of said nozzle.I have shown at the second crimping station 1 in detail in Fig. 28crimping means mounted on said standard to function with said adjacentmandrel to perfect said first crimping and seal said closure means intoa shipping position comprising a vertically reciprocal punch or pressmember |48 having the annular crimping portion |52 f thereonsubstantially identical in structure to shown in Fig. 25 for the firstcrimping station 4.

In place of the rst crimping station 4, flattening pivot forming station5, valve closing station 6 and final crimping station 1, I may performthe entire operation done at said stations at one station by providingmeans mounted on said standard to function with said adjacent mandrel ata single crimping and pivot forming station to simultaneously crimp theupper portion of said nozzle side wall 52 over the upper surface of saidvalve member and diametrically press the nozzle side walls inwardly atdiametric points thereof as at 59 to form a pivotal axis of rotation forsaid valve member. I have shown in Fig. 29 a. suitable type of means forthis purpose which comprises a vertically reciprocal punch sleeve |12having slidably mountedtherein, a supplemental punch shaft |14 havingthe upper ends |16 of pressingA cams |18 pivotally mounted thereon as at|88 at diametrically opposite points thereof and having the pivotforming sockets |82 on the inner surfaces of the lower ends thereof. Atdiametric points thereof, said slidable punch shaft |14 is provided withsuitable recesses |84 to receive the springs |86 therein to tend topivot the cam members |18 outwardly at all times. With this constructionit is obvious that the pivot shaft |14 may be lowered so that theannular crimping edge |52 thereof may a'but the upper portion 52 of saidhollow nozzle side wall to crimp it over the upper surface of said valvemember as the upper valve seat portion 46, and after said crimpingsurface |52 has started to function the outer punch sleeve |12 may beslid downwardly over said punch shaft |14 compressing the cam. members|18 inwardly to cause the pivot forming sockets |82 thereof to press thenozzle side wall inwardly at diametric points thereof to form theflattened sides 59 to provide a pivotal axis of rotation 36 for saidvalve member 32, the pivot lugs 60 sinking in the sockets 66 of saidnozzle side wall portion for this purpose.

It is apparent however in this assembly apparatus that if desired, thewasher loading station may be dispensed with and the valve closingstation 6 and the second crimping station 1 may, if desired, be alsodispensed with or that the four stations, namely numbers 4, 5, 8, and 1may be combined into one station in a manner hitherto described. Whenperforming the steps of crimping and inwardly pressing simultaneously,the turning lug 38 may be in upright position aligning the dischargepassage 34 with the ends 22 and 40 of said nozzle, it being no longernecessary for a second crimping as the sleeve |12 may be withdrawn tofree the outwardly impelled socket forming pivoted surfaces |82 from thediametrically opposite sides of said hollow nozzle wall prior towithdrawing the crimping shaft |14 from said upper valve seat formingportion 46. It is apparent however that the effect of giving the uppervalve seat portion a final separate crimp to rmly keep the valve inclosed position for shipping purposes is not possible where all stepsare combined in one. It is thus obvious that I have provided a noveltype of nozzle closure means for containers, bottles, tubes, cans andthe like having various novel features therein speciiically designed forease of manufacture of both nozzle member and valve member thereof andease of assembly thereof, a novel valve member for this purpose and anovel method of its manufacture, a novel type o1' extrusion apparatus toextrude the nozzle in a novel method and forming a novel intermediatenozzle product, and a novel process of assembly as well as an entireprocess of manufacture of said nozzle closure means and a novelapparatus for assembling the Valve closure member within the valve seatof the nozzle portion thereof with the advantages carefully explainedabove.

The method of manufacturing closure means for a container. whichcomprises pressure shaping a blank of ductile material to form a nozzleand around an at least partially spherical nozzle closure member havinga turning lug thereon and axis fforming means located diametricallythereof the method comprising at least two stages in the first stage ofwhich the ductile metal blank is pressure-shaped to form the nozzle andthe inner wall thereof shaped to approximately the shape of the valveseat for the closure member and thereafter the closure member isdisposed in position on said valve seat with the turning lug extendingthrough the outer end of the nozzle and the ductile metal is furtherpressure-shaped to form a partially. spherical valve seat on the innerwall of said nozzle extending around, and partially over said closuremember, with said turning ,lug projecting outwardly through the outerend of said nozzle; and diametrically opposite portions of said nozzlewall only are gently pressed inwardly against said diametricallyopposite axis of oscillation forming valve portions to form bearing andretaining means diametrically of the inner wall of said valve seat inassociation with said axis forming means located diametrically of saidclosure member.

8. The method of manufacturing closure means for a container, whichcomprises pressure shaping a blank of ductile material to form a nozzleand around an at least partially spherical nozzle closure member havinga turning lug thereon and axis forming means located diametricallythereof; the method comprising at least two stages in the first stage ofwhich the ductile metal blank is pressure shaped to form the nozzle, andthereafter diametrically opposite portions of said nozzle wall only aregently pressed inwardly adjacent said diametrically opposite axis ofoscillation forming valve portions to form bearing and retaining meansdiametrically of the inner wall of said nozzle in association with saidaxis forming means located diametrically of said closure member, and theclosure member Iis disposed in position in said nozzle with the turninglug extending through the outer end of the nozzle and the ductile metalis further pressureshaped to form a partially spherical valve seat onthe inner Wall of said nozzle extending around. and partially over saidclosure member, with said turning lug projecting outwardly through theouter end of said nozzle.

9. The method of manufacturing closure `means for a container, whichcomprises pressure shaping a blank of ductile material to form a nozzleand around an at least partially spherical nozzle closure member havinga turning lug thereon and axis forming means located diametricallythereon; to form a partially spherical valve seat on the inner wall of.said nozzle extending around, and partially over said closure member,with said turning lug projecting outwardly through the outer end of saidnozzle; and diametrically opposite portions of said nozzle wall only aregently pressed inwardly adjacent said diametrically opposite axis ofoscillation forming valve portions to form bearing means diametricallyof the inner wall of said valve seat in association with said axisforming means located diametrically of said closure member.

10. The method of manufacturing closure means for a container, ivhichcomprises pressure shaping a blank of ductile material to form a nozzleand around an at least partially spherical nozzle closure member havinga turning lug thereon and axis forming means located diametricallythereof; the method comprising at least two stages in the rst stage ofwhich the ductile metal blank is pressure shaped to form the nozzle andprovided with a washer receiving recess on the inner surface of the wallthereof. and thereafter diametrically opposite portions of said nozzlewall only are gently pressed in- Wardly adjacent said diametricallyopposite axis of oscillation forming valve portions to form bearing andretaining means diametrically of the inner wall of said nozzle inassociation with said axis forming means located diametrically of saidclosure member, and the washer is nserted in said recess and the closuremember is disposed in position in said nozzle with the turning lugextending through the outer end of the nozzle and the ductile metal isfurther pressure-shaped to form a partially spherical valve seat on theinner wall of said nozzle extending around, and partially over saidclosure member, with said turning lug projecting outwardly through theouter end of said nozzle.
